Hi,
this is already the second time that this bug happens to me (kinda stupid of me), but i wanted to let you know.
Steps to reproduce: (its even hard, because you need perfect timing)
Search for a competive match.
Load a highlight of previous matches.
The loading of the highlight is done and just in this moment you join a comp. game.
Now you are stuck in the VS Screen and can not select anything, you will get a penalty for either leaving or being inactive because you cant select a hero.
SR looses and time ban 10 minutes.
Cheers
